Accepting up to 8 channels of baseband or Dolby® Digital (AC-3) encoded audio via AES or HD/SD-SDI I/O, LQ-1000 provides simultaneous LKFS loudness measurement for two independent programs (5.1+2) per ITU-R BS.1770-3 and EBU R128 standards. Dolby Digital Plus and Dolby E decoding is optionally available.

The vibrant front-panel display features a large, color-coded numeric loudness value for the primary 5.1-channel program or secondary 2-channel program. The secondary meter can also be used to display loudness values for an internally created Lo/Ro or Lt/Rt downmix.

Additional bar graph meters with adjustable integration times, a loudness histogram to track loudness trends, True Peak readings, and dialnorm and coding information is also displayed.

Additionally, LQ-1000 provides comprehensive logging to a USB or network drive allowing stations to keep records of their loudness measurements.

A rear-panel VGA output allows information to be viewed on an external monitor or multi-viewer.




Next Generation PCM and Dolby® Encoded Audio Generation and Analysis. The Linear Acoustic MT2000 Multichannel Bitstream Analyzer is an efficient tool for end-to-end system testing and is the ideal next generation replacement for the original Dolby® DM100.

The Linear Acoustic MT2000 Bitstream Analyzer is a portable, handheld diagnostic tool that can monitor and generate Dolby Digital, Dolby Digital Plus, Dolby E, and PCM bitstreams. With its built-in test-signal generator, the MT2000 allows audio system integrators and service engineers to quickly monitor and check the integrity and composition of Dolby encoded and PCM signals routed through production, broadcast, cable, and satellite facilities, or even a home theater system.

The Linear Acoustic MT2000 accepts signals via AES, TOSLINK™ Optical, HD/SD-SDI, DVB-ASI, and MADI I/O plus HDMI in. The unit identifies the format of the selected input signal and activates the appropriate built-in decoder. Monitoring capabilities include error detection at the AES3 layer and within the coded audio layers, including SMPTE 337 formatting information and Dolby E guard band position.
